Transcript

hello students in this lesson let us study about the turnouts and its components turnouts and how exactly we delay our turnouts all these things will be starting in this particular lesson okay so to get started with turnout are nothing but the complete setup of points and crossings a complete set of points and crossings we know that points and cros...

Key Insights

• 👣 Turnouts are essential for diverting trains from the main track to a branch track or siding.
• 🚃 Components of turnouts include stock rails, tongue rails, lead rails, check rails, v crossing, stretcher bar, and slide chairs.
• 🫱 There are two types of turnouts: right-hand and left-hand, depending on their turning direction.
• 🖐️ Turnouts can be laid using through sleepers or interlaced sleepers.
• 🫥 Through sleepers allow for the same level of tracks on both the main and branch lines.
• 👣 Interlaced sleepers have advantages in maintaining track levels and packing, but can be difficult to manufacture and handle.
• 🚂 Proper packing and alignment of turnouts is crucial for smooth train movement.

Questions & Answers

Q: What is a turnout and what is its purpose?

A turnout is a setup of points and crossings that allows trains to switch from the main track to a branch track or siding.

Q: How are right-hand and left-hand turnouts different?

Right-hand turnouts turn towards the right direction, while left-hand turnouts turn towards the left direction.

Q: What are the functions of the stock rails and tongue rails?

Stock rails facilitate the smooth working of tongue rails, while tongue rails are used to divert the train from the main to the branch track.

Q: Why are check rails provided in turnouts?

Check rails are provided to check whether the wheels are climbing properly and ensure smooth movement of the train.

• Turnouts are a complete setup of points and crossings used to divert trains from the main track to a branch track or siding.

• There are two types of turnouts: right-hand and left-hand, depending on their turning direction.

• The components of turnouts include stock rails, tongue rails, lead rails, check rails, v crossing, stretcher bar, and slide chairs.
